Suppose fis an entire function such that there is a number M such that Re(f(z)2 - Imf(z))2 s M for all z. Prove that f must bie Hint: Compare to exercises #8: if f and g are both entire, then so are f-g and gof. Find an appropriate g so that you may apply Liouville's theorem to the entire function gof
